Can you give examples for errors that make it not compile? Why do you - as a 
*user* of our software - even compile it with pedantic?

Have you ever worked on a big open source project? The code is written by many 
different people and while it's easy in *some* cases to fix such warnings, 
there are places where you cannot be sure whether this is actually a bug or 
not. Hence you leave it as-is for now since it's just a warning.

This is not true. Compilers are good enough to optimize these statements out, 
if they are able to emit a warning for them.

Being better is of course something we aim for. Patches welcome. I'd like to 
enable warning-as-errors in KDevelop code base eventually, maybe even pedantic 
warnings. But as usual, there are some far more pressing issues to resolve
